Definitions

  • the invention relates to a label sheet and a method and an apparatus for its production.
  • Label materials are generally made up of an adhesive backing material, a pressure sensitive adhesive and an outer material. They are produced by coating the carrier material or the upper material with the pressure sensitive adhesive and then carrying out a lamination with the upper material or the carrier material. The composite formed is then rolled up, the rolls often being trimmed on the side faces and possibly also cut into narrower rolls.
  • the rolled up label material is first unrolled in printing machines and, if necessary, printed.
  • the upper material and possibly also the carrier material are then punched in a predetermined pattern, and the punched-out upper material is drawn off as a grid matrix.
  • the individual label sheets are finally obtained from the punched and stripped endless tape by means of longitudinal cuts and cross sections or transverse perforations and then being deposited or unfolded and then separated at the perforation lines.
  • a solid medium is the combination of carrier material, pressure sensitive adhesive and upper material severed vertically.
  • the solid medium are knives rotating in the web running direction or transverse to the web running direction, a blade fixed in the web running direction or knives oscillating in the web running direction.
  • the problem with these cutting steps is that the solid cutting medium can tear PSA particles out of the cut edges. How strongly this problem occurs depends on the production speed (web running speed), the properties of the layer materials of the labels (e.g. tendency of the pressure sensitive adhesive to become brittle) and also the properties of the cutting medium (e.g. knife sharpness). These PSA particles torn out of the label material then stick to the cutting medium and to the cut edges of the label material. In particular, an adhesive adhering to the cutting knife causes an unclean cut, since it produces a rasp effect on the label sheet edges.
  • Label sheets with adhering, more or less loose pressure-sensitive adhesive particles and with unclean cut edges are undesirable if they are to be processed further by machine, since the adhering particles are stripped off by multiple contact with the corresponding machine parts and contaminate the further processing system.
  • the above disadvantageous effect occurs - albeit more slowly.
  • the label sheet is often under vertical pressure (for example during further transport) or under the influence of heat (for example during printing or through machine waste), which means that the pressure sensitive adhesive is applied over the smooth edges come out or bleed out and thereby come into contact with the machine parts.
  • Label sheets with unclean cut edges are particularly disruptive if they are further processed or printed on EDP printing machines, such as laser, ion, magnetic printers, ink-jet printers, thermal and transfer printers, as well as in copier and fax machines working according to these printing principles .
  • Adhesive adhesive particles stick to the machine parts of the transport route, e.g. Transport rollers, separation and guide plates, grippers, semiconductor drums, fixing rollers, firmly. Subsequent label sheets in turn stick to these stripped pressure-sensitive adhesive particles and are thus hindered in their running. The consequences are a delay or even a termination of the transport or a deflection of the label sheets from the normal transport route and thus an impairment of the further processing productivity and the print quality.
  • Pressure sensitive adhesive particles attached to the information-giving machine parts e.g. the semiconductor drum of a laser printer, stick, impair and prevent printing at these points.
  • Machine parts made of plastics e.g. Fusing rollers, or parts with highly sensitive surface layers, e.g. Semiconductor drums, are due to the continuous flow of label sheets or subsequent other print media, such as Copy paper, effective adhesive, tear and friction forces, which are caused by adhering PSA particles, gradually worn out and damaged.
  • the second known solution is to design the label sheet in such a way that the upper material along the cut edges at the edges in the web running direction is in each case approximately 0.5 mm narrower than the abhesive carrier material.
  • EDP printer When running these sheets over e.g. EDP printer is used where the abhesive backing material protrudes and on machine parts such as Baffles, transport rollers, semiconductor drums and fusing rollers, but do not transfer any pressure sensitive adhesive to them, since only the protruding edges of the carrier material free of pressure sensitive adhesive particles hit.
  • Another object is to create an economically productive method for producing such label sheets and a device suitable therefor.
  • An essential and critical step with regard to the production speed (economy) of The process for the production of label sheets is the matrix deduction of the upper material.
  • the punched-out matrix is lifted off the web as an endless grid belt via a deflection roller or a fixed edge in such a way that it has the same absolute speed as the web, but the speed component in the web running direction is below the web speed.
  • the grid is then wound up separately.
  • the deflection roller can be fixed, freely rotatable or driven.
  • the production speed depends crucially on the angle between the plane of the matrix grid belt and the plane of the carrier material at the take-off point, the size and the uniformity of the tension on the matrix grid belt between pull-off ⁇ place and winding acts, and the shape of the punched-out upper material matrix, ie the number or density of the longitudinal and transverse webs per label sheet, the length and width of the longitudinal and transverse webs, the type and shape of the nodes of longitudinal and Cross bars (rectangular, polygonal or round).
  • the separating force of the upper material from the abhesive carrier material is reduced in practice by heating the label material before the matrix grid is removed, e.g. the label material web runs over an electrically heated sheet. Heating the pressure sensitive adhesive usually reduces the separating force between the outer material and the abhesive backing material.
  • Another method for optimizing the production speed is to specifically set the angle between the take-off plane of the matrix grid belt and the web running direction of the further label material, since the size of the separating force between the upper material and the backing material also depends, among other things, on the take-off angle.
  • This method can also be modified in that the matrix lattice tape is additionally pulled off at an angle to the plane of the web running direction of the continued label material, ie at a certain angle to it and thus at different times from one long side to the other long side of the lattice.
  • the above task for creating an economical manufacturing process for label sheets can thus be specified to provide a process which avoids the above disadvantages of the known processes with regard to the removal of the matrix grid tape and is economically productive, i.e. can be carried out at high production speed or web running speed. Furthermore, a device suitable for this is to be provided.

Description

Etikettenbogen. Verfahren zur Herstellung und Vorrichtung Label sheet. Manufacturing method and device
BESCHREIBUNGDESCRIPTION
Die Erfindung betrifft einen Etikettenbogen und- ein Verfahren sowie eine Vorrichtung zu seiner Herstellung.The invention relates to a label sheet and a method and an apparatus for its production.
Etikettenmaterialien sind generell aus einem abhäsiven Trägermaterial, einem Haftklebstoff und einem Obermaterial aufgebaut. Sie werden hergestellt, indem man das Träger¬ material oder das Obermaterial mit dem Haftklebstoff beschichtet und anschließend eine La inierung mit dem Obermaterial bzw. dem Tr germaterial durchführt. Der gebildete Verbund wird anschließend aufgerollt, wobei die Rollen häufig an den Seitenflächen beschnitten und ggf. auch zu schmäleren Rollen geschnitten werden.Label materials are generally made up of an adhesive backing material, a pressure sensitive adhesive and an outer material. They are produced by coating the carrier material or the upper material with the pressure sensitive adhesive and then carrying out a lamination with the upper material or the carrier material. The composite formed is then rolled up, the rolls often being trimmed on the side faces and possibly also cut into narrower rolls.
Für die Herstellung von Etikettenbogen wird das aufge¬ rollte Etikettenmaterial zunächst in Druckmaschinen abgerollt und gegebenenfalls bedruckt. Anschließend wird das Obermaterial und ggf. auch das Trägermaterial in einem vorbestimmten Muster gestanzt, und das ausgestanzte Obermaterial wird als Gittermatrix abgezogen. Aus dem gestanzten und gestrippten Endlosband werden die einzelnen Etikettenbogen schließlich durch Längsschnitte und Querschnitte bzw. Querperforationen und anschließendes Ablegen bzw. Abfalten und anschließendes Trennen an den Perforationslinien erhalten.For the production of label sheets, the rolled up label material is first unrolled in printing machines and, if necessary, printed. The upper material and possibly also the carrier material are then punched in a predetermined pattern, and the punched-out upper material is drawn off as a grid matrix. The individual label sheets are finally obtained from the punched and stripped endless tape by means of longitudinal cuts and cross sections or transverse perforations and then being deposited or unfolded and then separated at the perforation lines.
Bei der obigen Herstellung werden Schneidschritte eingesetzt, wobei ein festes Medium den Verbund aus Trägermaterial, Haftklebstoff und Obermaterial vertikal durchtrennt. Beispiele für das feste Medium sind in Bahnlaufrichtung oder quer zur Bahnlaufrichtung rotierende Messer, eine in Bahnlaufrichtung feststehende Klinge oder in Bahnlaufrichtung oszillierende Messer.In the above production, cutting steps are used, whereby a solid medium is the combination of carrier material, pressure sensitive adhesive and upper material severed vertically. Examples of the solid medium are knives rotating in the web running direction or transverse to the web running direction, a blade fixed in the web running direction or knives oscillating in the web running direction.
Bei diesen Schneidschritten besteht das Problem, daß das feste Schneidmedium Haftklebstoffpartikel aus den Schnitt¬ kanten herausreißen kann. Wie stark dieses Problem auf¬ tritt, hängt von der Produktionsgeschwindigkeit (Bahnlauf- geschwindigkeit) , den Eigenschaften der Schichtmaterialien der Etiketten (z.B. Versprödungsneigung des Haftkleb¬ stoffes) und auch den Eigenschaften des Schneidmediums (z.B. Messerschärfe) ab. Diese aus dem Etikettenmaterial herausgerissenen Haftklebstoffpartikel bleiben dann an dem Schneidmedium und an den Schnittkanten des Etiketten¬ materials kleben. Insbesondere ein am Schneidmesser anhaftender Klebstoff bewirkt einen unsauberen Schnitt, da er eine Raspelwirkung an den Etikettenbogenkanten erzeugt.The problem with these cutting steps is that the solid cutting medium can tear PSA particles out of the cut edges. How strongly this problem occurs depends on the production speed (web running speed), the properties of the layer materials of the labels (e.g. tendency of the pressure sensitive adhesive to become brittle) and also the properties of the cutting medium (e.g. knife sharpness). These PSA particles torn out of the label material then stick to the cutting medium and to the cut edges of the label material. In particular, an adhesive adhering to the cutting knife causes an unclean cut, since it produces a rasp effect on the label sheet edges.
Etikettenbogen mit anhaftenden, mehr oder weniger losen Haftklebstoffpartikeln und mit unsauberen Schnittkanten sind unerwünscht, wenn sie maschinell weiterverarbeitet werden sollen, da die anhaftenden Teilchen durch viel¬ fältige Berührung mit den entsprechenden Maschinenteilen abgestreift werden und die Weiterverarbeitungsanlage verunreinigen.Label sheets with adhering, more or less loose pressure-sensitive adhesive particles and with unclean cut edges are undesirable if they are to be processed further by machine, since the adhering particles are stripped off by multiple contact with the corresponding machine parts and contaminate the further processing system.
Auch wenn Etikettenbogen mit sauberen bzw. glatten Schnittkanten verarbeitet werden, tritt der obige nachteilige Effekt - wenn auch langsamer - auf. Bei der Weiterverarbeitung steht der Etikettenbogen häufig unter vertikalem Druck (z.B. beim Weitertransport) oder unter Wärmeeinwirkung (z.B. beim Bedrucken oder durch Maschinenabwär e) , wodurch der Haftklebstoff über die glatten Kanten hinaus austritt bzw. ausblutet und dadurch mit den Maschinenteilen in Berührung kommt.Even if label sheets are processed with clean or smooth cut edges, the above disadvantageous effect occurs - albeit more slowly. During further processing, the label sheet is often under vertical pressure (for example during further transport) or under the influence of heat (for example during printing or through machine waste), which means that the pressure sensitive adhesive is applied over the smooth edges come out or bleed out and thereby come into contact with the machine parts.
Besonders störend wirken Etikettenbogen mit unsauberen Schnittkanten, wenn sie über EDV-Druckmaschinen, wie Laser-, Ionen-, Magnetdrucker, Ink-Jet-Drucker, Thermo- und Transferdrucker, sowie in nach diesen Druckprinzipien arbeitenden Kopier- und Faxgeräten weiterverarbeitet bzw. bedruckt werden. Anhaftende Klebstoffpartikel kleben auf den Maschinenteilen des Transportweges, wie z.B. Trans¬ portwalzen, Separations- und Leitblechen, Greifern, Halbleitertrommeln, Fixierwalzen, fest. Nachfolgende Etikettenbogen kleben wiederum an diesen abgestreiften Haftklebstoffpartikeln und werden so in ihrem Lauf behindert. Die Folgen sind eine Verzögerung oder sogar ein Abbruch des Transports oder eine Ablenkung der Etiketten¬ bogen von dem normalen Transportweg und damit eine Beein¬ trächtigung der Weiterverarbeitungsproduktivität und der Druckqualität. Haftklebstoffpartikel, die an den informa- tionsgebenden Maschinenteilen, wie z.B. der Halbleiter¬ trommel eines Laserdruckers, kleben, beeinträchtigen und verhindern an diesen Stellen den Druck. Aus Kunststoffen bestehende Maschinenteile, wie z.B. Fixierwalzen, oder hochempfindliche Oberflächenschichten aufweisende Teile, wie z.B. Halbleitertrommeln, werden durch die ständig beim Durchlauf von Etikettenbogen oder nachfolgende andere Druckträger, wie z.B. Kopierpapier, wirksamen Adhäsions- Reiß- und Reibungskräfte, die durch anhaftende Haftkleb- stoffpartikel bedingt sind, allmählich abgenutzt und beschädigt.Label sheets with unclean cut edges are particularly disruptive if they are further processed or printed on EDP printing machines, such as laser, ion, magnetic printers, ink-jet printers, thermal and transfer printers, as well as in copier and fax machines working according to these printing principles . Adhesive adhesive particles stick to the machine parts of the transport route, e.g. Transport rollers, separation and guide plates, grippers, semiconductor drums, fixing rollers, firmly. Subsequent label sheets in turn stick to these stripped pressure-sensitive adhesive particles and are thus hindered in their running. The consequences are a delay or even a termination of the transport or a deflection of the label sheets from the normal transport route and thus an impairment of the further processing productivity and the print quality. Pressure sensitive adhesive particles attached to the information-giving machine parts, e.g. the semiconductor drum of a laser printer, stick, impair and prevent printing at these points. Machine parts made of plastics, e.g. Fusing rollers, or parts with highly sensitive surface layers, e.g. Semiconductor drums, are due to the continuous flow of label sheets or subsequent other print media, such as Copy paper, effective adhesive, tear and friction forces, which are caused by adhering PSA particles, gradually worn out and damaged.
Um diese Nachteile zu vermeiden, wurden bislang zwei verschiedene Lösungswege verfolgt. Gemäß der in EP-A-0 255 396 beschriebenen Lösung werden die äußeren Schnittkanten des Etikettenbogens mit einem Lack beschichtet, der nach der Aushärtung bewirkt, daß mehr oder weniger lose an den Kanten haftende Haftkleb- stoffpartikel gebunden werden, und daß unter den Weiter¬ verarbeitungsbedingungen kein Haftklebstoff über die Kanten hinaus austreten bzw.* ausbluten kann.To avoid these disadvantages, two different solutions have been pursued so far. According to the solution described in EP-A-0 255 396, the outer cut edges of the label sheet are coated with a varnish which, after curing, causes more or less loose adhesive particles to adhere to the edges, and that under the further Processing conditions no pressure sensitive adhesive can leak out or * bleed out.
Nachteile dieses Verfahrens bestehen darin, daß ein zusätzlicher Beschichtungs- und Aushärtungsschritt erforderlich ist, das Etikettenprodukt mit zusätzlichen Chemikalien behandelt wird, was aus gesundheitlichen oder umweltbedingten Gründen unerwünscht ist, und daß bei unbeabsichtigtem Ablösen eines Randetiketts bei der Weiterverarbeitung der Effekt der Haftklebstoffaustritt¬ sperre aufgehoben wird.Disadvantages of this method are that an additional coating and curing step is required, the label product is treated with additional chemicals, which is undesirable for health or environmental reasons, and that if an edge label is accidentally removed during further processing, the effect of the pressure-sensitive adhesive outlet barrier is eliminated becomes.
Die zweite bekannte Lösung besteht darin, den Etiketten¬ bogen derart zu gestalten, daß das Obermaterial entlang der Schnittkanten an den Rändern in Bahnlaufrichtung jeweils um etwa 0,5 mm schmäler ist als das abhäsive Trägermaterial. Beim Lauf dieser Bögen über z.B. EDV-Drucker wird dort, wo das abhäsive Trägermaterial übersteht und an Maschinenteile, wie z.B. Leitbleche, Transportwalzen, Halbleitertrommeln und Fixierwalzen, anstößt, kein Haftklebstoff auf diese übertragen, da nur die von Haftklebstoffpartikeln freien, vorstehenden Trägermaterialkanten anstoßen.The second known solution is to design the label sheet in such a way that the upper material along the cut edges at the edges in the web running direction is in each case approximately 0.5 mm narrower than the abhesive carrier material. When running these sheets over e.g. EDP printer is used where the abhesive backing material protrudes and on machine parts such as Baffles, transport rollers, semiconductor drums and fusing rollers, but do not transfer any pressure sensitive adhesive to them, since only the protruding edges of the carrier material free of pressure sensitive adhesive particles hit.
Nachteile der nach dem obigen Verfahren hergestellten Produkte bestehen darin, daß die vorstehende Träger¬ materialkante nur längs, d.h. in Bahnlaufrichtung, produziert wird, sodaß der Klebstoffaustritt und -transfer nur an zwei Kanten (Längskanten) vermieden wird, nichtDisadvantages of the products produced by the above process are that the protruding edge of the carrier material is only longitudinal, i.e. in the direction of web travel, so that adhesive leakage and transfer is only avoided on two edges (longitudinal edges), not
ERSÄΓZBLÄΓT (REGEL 26) aber an den beiden anderen Kanten (Querkanten) des Etikettenbogens. Dementsprechend müssen, je nachdem ob der Etikettenbogen mit der schmalen oder der breiten Seite voran durch die Weiterverarbeitungsanlage (z.B. EDV- Drucker) transportiert wird, zwei verschiedene Produkte bereitgehalten werden, da das Auftreffen der voraneilenden Kante auf eine Transportwalze, Halbleitertrommel oder eine Fixierwalze bezüglich des Haftklebstofftransfers besonders kritisch ist. Es gibt eine beträchtliche Anzahl von Kopiergeräten, die den Etikettenbogen sowohl mit der breiten als auch der schmalen Seite voran einziehen und durchführen. Laserdrucker ziehen die Etikettenb gen überwiegend mit der schmalen Seite voran ein. Kopiergeräte und Laserdrucker sind heute allgemein übliche Druck- und Vervielfältigungsgeräte im Büro und stehen häufig neben¬ einander zur Anwendung, sodaß ein Einziehen des Etiketten¬ bogens auf all diesen Geräten immer mit der gleichen Seite voran nicht möglich bzw. vorteilhaft ist.ERSÄΓZBLÄΓT (RULE 26) but on the other two edges (transverse edges) of the label sheet. Accordingly, depending on whether the label sheet is transported with the narrow or the wide side first through the further processing system (e.g. computer printer), two different products must be kept ready, since the impact of the leading edge on a transport roller, semiconductor drum or a fixing roller with regard to the Pressure sensitive adhesive transfers is particularly critical. There are a significant number of copiers that feed and feed the label sheet with both the wide and the narrow side first. Laser printers mostly pull in the label sheets with the narrow side first. Copiers and laser printers are common printing and duplicating devices in the office today and are often used side by side, so that pulling in the label sheet on all these devices with the same side is not always possible or advantageous.
Eine Aufgabe der vorliegenden Erfindung besteht somit darin, einen Etikettenbogen zu schaffen, mit dem die oben beschriebenen Nachteile, insbesondere die Übertragung von Haftklebstoffpartikeln auf die Maschinenteile einer Weiterverarbeitungsanlage, mit denen die Bogenkanten in Berührung kommen, vermieden werden, unabhängig davon, mit welcher Seite der Etikettenbogen in die Weiterverarbei¬ tungsanlage eingezogen wird.It is therefore an object of the present invention to provide a label sheet with which the disadvantages described above, in particular the transfer of pressure-sensitive adhesive particles to the machine parts of a further processing system with which the sheet edges come into contact, are avoided, regardless of which side of the sheet Label sheet is drawn into the further processing system.
Eine weitere Aufgabe besteht darin, ein wirtschaftlich produktives Verfahren zur Herstellung solcher Etiketten¬ bogen und eine dazu geeignete Vorrichtung zu schaffen.Another object is to create an economically productive method for producing such label sheets and a device suitable therefor.
Ein wesentlicher und kritischer Schritt bezüglich der Produktionsgeschwindigkeit (Wirtschaftlichkeit) der Verfahren zur Herstellung von Etikettenbogen ist der Matrixabzug des Obermaterials. Die herausgestanzte Matrix wird als endloses Gitterband über eine Umlenkwalze oder eine feststehende Kante so von der Bahn abgehoben, daß sie die gleiche absolute Geschwindigkeit wie die Bahn hat, die Geschwindigkeitskomponente in Bahnlaufrichtung jedoch unter der Bahngeschwindigkeit liegt. Das Gitter wird dann separat aufgewickelt. Die Umlenkwalze kann feststehend, frei drehbar oder angetrieben sein. Bei gegebenem Ober¬ material und gegebener Trennkraft des Obermaterials von dem abhäsiven Trägermaterial hängt die Produktionsge- schwindigkeit entscheidend vom Winkel zwischen der Ebene des Matrixgitterbandes und der Ebene des Trägermaterials an der Abzugsstelle, der Größe und der Gleichmäßigkeit der Spannung, die auf das Matrixgitterband zwischen Abzugs¬ stelle und Aufwicklung wirkt, und der Form der herausge- stanzten Obermaterialmatrix, d.h. von der Anzahl bzw. Dichte der Längs- und Querstege pro Etikettenbogen, der Länge und Breite der Längs- und Querstege, der Art und Ausformung der Knotenpunkte von Längs- und Querstegen (rechtwinklig, vieleckig oder rund) ab.An essential and critical step with regard to the production speed (economy) of The process for the production of label sheets is the matrix deduction of the upper material. The punched-out matrix is lifted off the web as an endless grid belt via a deflection roller or a fixed edge in such a way that it has the same absolute speed as the web, but the speed component in the web running direction is below the web speed. The grid is then wound up separately. The deflection roller can be fixed, freely rotatable or driven. For a given upper material and a given separation force of the upper material from the abhesive carrier material, the production speed depends crucially on the angle between the plane of the matrix grid belt and the plane of the carrier material at the take-off point, the size and the uniformity of the tension on the matrix grid belt between pull-off ¬ place and winding acts, and the shape of the punched-out upper material matrix, ie the number or density of the longitudinal and transverse webs per label sheet, the length and width of the longitudinal and transverse webs, the type and shape of the nodes of longitudinal and Cross bars (rectangular, polygonal or round).
Um eine erhöhte Produktionsgeschwindigkeit zu erreichen, die für ein wirtschaftliches Herstellverfahren erforder¬ lich ist, wird in der Praxis die Trennkraft des Ober¬ materials von dem abhäsiven Trägermaterial durch Erwärmen des Etikettenmaterials vor dem Abzug des Matrixgitters reduziert, indem man z.B. die Etikettenmaterialbahn über ein elektrisch beheiztes Blech führt. Durch Erwärmen des Haftklebstoffes wird dabei gewöhnlich die Trennkraft zwischen Obermaterial und abhäsivem Trägermaterial reduziert.In order to achieve an increased production speed, which is necessary for an economical manufacturing process, the separating force of the upper material from the abhesive carrier material is reduced in practice by heating the label material before the matrix grid is removed, e.g. the label material web runs over an electrically heated sheet. Heating the pressure sensitive adhesive usually reduces the separating force between the outer material and the abhesive backing material.
Mit einem solchen Verfahren sind jedoch die Nachteile verbunden, daß die ursprünglich eingestellte Trennkraft zwischen Obermaterial und Trägermaterial nach dem Erwärmen und Wiederabkühlen verändert werden kann. Ein weiterer Nachteil ist darin zu sehen, daß die Erwärmung des Eti¬ kettenmaterials und damit die Trennkraft zwischen Ober¬ material und Trägermaterial bei Schwankung der Produk¬ tionsgeschwindigkeit (Bahnlaufgeschwindigkeit) ebenfalls stark schwanken kann. Schließlich wird durch dieses Ver¬ fahren die Trennkraft an allen Stellen des Etiketten¬ materials herabgesetzt, sodaß sich auch die auf "dem abhäsiven Trägermaterial nach Abzug der Matrix verblei¬ benden Obermaterialflächen (einzelne Etiketten), besonders bei anschließenden Umlenkungen der Endlosbahn, leicht ablösen oder bei nicht vollkommen exakter Durchstanzung des Obermaterials an der Stelle der Stanzlinie bei Abzug der Matrix leicht mit angehoben werden. Weiterhin ist auch ein Nachteil darin zu sehen, daß das Verfahren bei bestimmten Etikettenprodukten nicht anwendbar ist, nämlich dann, wenn durch Erwärmen die Trennkraft zwischen Obermaterial und Trägermaterial gesteigert wird.However, such a method has the disadvantages that the separation force originally set can be changed between the upper and the base material after heating and cooling. A further disadvantage is the fact that the heating of the label material and thus the separating force between the upper material and the carrier material can also fluctuate greatly when the production speed (web speed) fluctuates. Finally, pass through this compounds according to the separation force at all points of Etiketten¬ materials reduced, is so also to "the abhesive substrate material, after deduction of the matrix verblei¬ reproduced upper surfaces (individual labels), especially with subsequent deflections of the continuous web, slightly detached or if the upper material is not punched out exactly at the point of the punching line when the matrix is removed, there is also a disadvantage that the method cannot be used with certain label products, namely when the separation force between the upper material is caused by heating and carrier material is increased.
Ein anderes Verfahren zur Optimierung der Produktionsge- schwindigkeit hebt darauf ab, den Winkel zwischen der Abzugsebene des Matrixgitterbandes und der Bahnlaufrich¬ tung des weitergeführten Etikettenmaterials spezifisch einzustellen, da die Größe der Trennkraft zwischen Obermaterial und Trägermaterial unter anderem auch vom Abzugswinkel abhängt. Dieses Verfahren kann noch dadurch modifiziert werden, daß das Matrixgitterband zusätzlich schräg zur Ebene der Bahnlaufrichtung des weitergeführten Etikettenmaterials, d.h. in einem bestimmten Winkel hierzu und somit zeitlich versetzt von einer Längsseite zu der anderen Längsseite des Gitters, abgezogen wird. Mit dem obigen Verfahren ist es jedoch noch nicht möglich, die Trennkraft zwischen Obermaterial und abhäsivem Tr ger¬ material so weit zu reduzieren und die zwischen Längs- und Querstegen des Matrixgitters beim Abzug auftretenden Spannungen so weit abzubauen, daß Matrices mit dünnen Längs- und Querstegen, insbesondere aber mit sehr dünnen Querstegen, abgezogen werden können, ohne daß diese reißen und auf dem Träger- oder Obermaterial des in Bahnlauf¬ richtung weitergeführten Etikettenmaterials haften bleiben, die Weiterverarbeitung somit beeinträchtigen und stören oder gar zu einem Maschinenstop führen können.Another method for optimizing the production speed is to specifically set the angle between the take-off plane of the matrix grid belt and the web running direction of the further label material, since the size of the separating force between the upper material and the backing material also depends, among other things, on the take-off angle. This method can also be modified in that the matrix lattice tape is additionally pulled off at an angle to the plane of the web running direction of the continued label material, ie at a certain angle to it and thus at different times from one long side to the other long side of the lattice. With the above method, however, it is not yet possible to reduce the separating force between the upper material and the abhesive backing material so far and that between the longitudinal and Reduce cross bars of the matrix lattice when tension is removed so that matrices with thin longitudinal and cross bars, but especially with very thin cross bars, can be removed without tearing and sticking to the carrier or upper material of the label material continued in the direction of web travel remain, thus impairing and disrupting further processing or even leading to a machine stop.
Die obige Aufgabe zur Schaffung eines wirtschaftlichen Herstellverfahrens für Etikettenbogen läßt sich somit dahingehend präzisieren, ein Verfahren zur Verfügung zu stellen, das die obigen Nachteile der bekannten Verfahren hinsichtlich des Abzugs des Matrixgitterbandes vermeidet und wirtschaftlich produktiv, d.h. mit hoher Produktions¬ geschwindigkeit bzw. Bahnlaufgeschwindigkeit, durchgeführt werden kann. Weiterhin soll eine hierfür geeignete Vorrichtung bereitgestellt werden.The above task for creating an economical manufacturing process for label sheets can thus be specified to provide a process which avoids the above disadvantages of the known processes with regard to the removal of the matrix grid tape and is economically productive, i.e. can be carried out at high production speed or web running speed. Furthermore, a device suitable for this is to be provided.
Die erstgenannte Aufgabe wird mittels eines Etiketten¬ bogens aus einem Etikettenmaterial, bestehend aus abhä¬ sivem Trägermaterial, zwischenliegender Haftklebstoff¬ schicht und Obermaterial, gelöst, der dadurch gekenn¬ zeichnet ist, daß die Fläche des Obermaterials derart kleiner als die des Trägermaterials ist, daß die Trägermaterialkante auf allen Seiten des Bogens über die Obermaterialkante hinaussteht.The first-mentioned object is achieved by means of a label sheet made of a label material, consisting of abhesive carrier material, intermediate pressure-sensitive adhesive layer and upper material, which is characterized in that the area of the upper material is so smaller than that of the carrier material that the backing edge protrudes beyond the face edge on all sides of the sheet.
Gemäß einer bevorzugten Ausführungsform beträgt der Abstand zwischen der Trägermaterialkante und der Ober¬ materialkante 0,1 bis 2,0 mm, wobei 0,2 bis 1,0 mm insbesondere bevorzugt sind.According to a preferred embodiment, the distance between the carrier material edge and the upper material edge is 0.1 to 2.0 mm, 0.2 to 1.0 mm being particularly preferred.
Der Etikettenbogen ist weiterhin vorzugsweise rechteckig ausgebildet. Gemäß einer besonderen Ausführung ist die Trägermaterial¬ fläche und/oder die Obermaterialfläche des Etikettenbogens bedruckt, beschichtet, geschnitten, gestanzt und/oder perforiert.The label sheet is also preferably rectangular. According to a special embodiment, the carrier material surface and / or the upper material surface of the label sheet is printed, coated, cut, punched and / or perforated.
Hierbei kann die Obermaterialfläche durch Schneiden, Stanzen und/oder Perforieren in einzelne Teilfächen aufgeteilt sein. Weiterhin können einzelne Teilflächen des Obermaterials des Etikettenbogens (Matrix) abgezogen sein. Eine weitere spezielle Ausführungsform sieht vor, daß das Obermaterial zwischen den einzelnen Teilfächen (Matrix) abgezogen ist.The surface of the upper material can be divided into individual partial areas by cutting, punching and / or perforating. Furthermore, individual partial areas of the upper material of the label sheet (matrix) can be removed. Another special embodiment provides that the upper material between the individual partial areas (matrix) is removed.
Die oben genannten Teilflächen sind vorzugsweise drei¬ eckig, rechteckig, quadratisch, vieleckig, rund oder oval. Bei rechteckigen und quadratischen Teilflächen weisen diese vorzugsweise rechteckige, gleichmäßig vielkantige oder runde Ecken auf.The partial areas mentioned above are preferably triangular, rectangular, square, polygonal, round or oval. In the case of rectangular and square partial surfaces, these preferably have rectangular, uniformly polygonal or round corners.
Vorzugsweise entspricht die Fläche des Trägermaterials des Etikettenbogens DIN AO bis DIN A6, wobei DIN A3 bis DIN A5 bevorzugt ist, und DIN A4 ganz besonders bevorzugt ist.The area of the carrier material of the label sheet preferably corresponds to DIN AO to DIN A6, with DIN A3 to DIN A5 being preferred and DIN A4 being very particularly preferred.
Das Etikettenmaterial des Etikettenbogens weist vorzugs- weise ein Flachengewicht von 80 bis 300 g/m 2 auf, wobeiThe label material of the label sheet preferably has a basis weight of 80 to 300 g / m 2, where
.. . . 2 ein Flachengewicht von 120 bis 200 g/m besonders günstig ist.... . 2 a basis weight of 120 to 200 g / m is particularly favorable.
Das abhäsive Trägermaterial des Etikettenbogens besteht vorzugsweise aus Papier, Karton, einer Kunststoff- oder Metallfolie oder deren Verbünde und besitzt mindestens an der dem Haftklebstoff zugewandten Seite ein Trennmittel, das vorzugsweise durch Silikon dargestellt ist. Der Haftklebstoff für den Etikettenbogen wird bevorzugt aus Kautschuk, Poly( eth)acrylat, Polyvinylderivat oder einem Copolymer hiervon, Polyamid, Copolyamid, Polyester, Copolyester, Copolyether, Polyurethan, Polyepoxid oder Polysiloxan oder Mischungen hiervon ausgewählt.The adhesive backing material of the label sheet preferably consists of paper, cardboard, a plastic or metal foil or their composites and has at least on the side facing the pressure sensitive adhesive a release agent, which is preferably represented by silicone. The pressure sensitive adhesive for the label sheet is preferably selected from rubber, poly (eth) acrylate, polyvinyl derivative or a copolymer thereof, polyamide, copolyamide, polyester, copolyester, copolyether, polyurethane, polyepoxide or polysiloxane or mixtures thereof.
Das Obermaterial des Etikettenbogens wird vorzugsweise durch Papier, Karton, Kunststoff- oder Metallfolien bzw. deren Verbünde dargestellt.The upper material of the label sheet is preferably represented by paper, cardboard, plastic or metal foils or their composites.
Ein Etikettenbogen der oben genannten Art überträgt bei der Verarbeitung auf Kopierern und EDV-Druckern keinen Haftklebstoff auf Maschinenteile, mit denen die Bogen- ränder in Berührung kommen, unabhängig davon, ob er mit der schmalen oder breiten Seite eingezogen und durchge¬ führt wird. Der erfindungsgemäße Etikettenbogen ist auch auf allen anderen Weiterverarbeitungsanlagen (z.B. Druck¬ maschinen) einsetzbar, unabhängig davon, mit welcher Seite er eingezogen und durchgeführt wird, ohne daß auf ein Maschinenteil Haftklebstoffpartikel übertragen werden. Weiterhin wird der Lauf nachfolgender Etikettenbogen nicht durch zurückgelassene Haftklebstoffpartikel beeinträchtigt. Der Etikettenbogen kann nach dem Durchlauf durch Kopierer, EDV-Drucker oder eine andere Weiterverarbeitungsanlage leicht abgelegt werden, er verblockt nicht im Stapel und läßt sich vom Stapel per Hand leicht separieren, da keine Verblockung durch über die Schnittkanten des Etiketten¬ bogens ausgetretenen Haftklebstoff oder durch anhaftende Haftklebstoffpartikel erfolgt.When processed on copiers and computer printers, a label sheet of the type mentioned above does not transfer any pressure-sensitive adhesive to machine parts with which the sheet edges come into contact, regardless of whether it is drawn in and carried out with the narrow or wide side. The label sheet according to the invention can also be used on all other further processing systems (e.g. printing machines), irrespective of the side with which it is drawn in and carried out without transferring pressure-sensitive adhesive particles to a machine part. Furthermore, the run of subsequent label sheets is not impaired by the pressure sensitive adhesive particles left behind. After passing through a copier, computer printer or other processing system, the label sheet can easily be put down, it does not block in the stack and can be easily separated from the stack by hand, since there is no blocking due to pressure-sensitive adhesive escaping over the cut edges of the label sheet or through adhering PSA particles.
Die zuletzt genannte Aufgabe bezüglich eines wirtschaft¬ lichen Herstellverfahrens für Etikettenbogen der oben genannten Art wird durch ein Verfahren gelöst, bei dem ein aus abhäsivem Trägermaterial, zwischenliegender Haftkleb¬ stoffschicht und Obermaterial aufgebautes Etiketten-The last-mentioned object with regard to an economical manufacturing method for label sheets of the above-mentioned type is achieved by a method in which a label made up of an abhesive carrier material, intermediate pressure-sensitive adhesive layer and outer material

Gemäß einer bevorzugten Ausführungsform wird der Winkel alpha auf einen Wert von 10-70°, und insbesondere auf einen Wert von 20-40° eingestellt.According to a preferred embodiment, the angle alpha is set to a value of 10-70 °, and in particular to a value of 20-40 °.
Das Abziehen der Matrix erfolgt vorzugsweise so, daß die äußeren Langsstege über je einen Niederhalter und über eine Matrixführungswalze, die für die Einstellung des obigen Winkels alpha entsprechend zueinander positioniert werden, geführt werden.The matrix is preferably pulled off in such a way that the outer longitudinal webs are each guided over a hold-down device and over a matrix guide roller, which are positioned in relation to one another for setting the above angle alpha.
Für den Fall, daß das Matrixgitterband innere Langsstege aufweist, werden bevorzugt zu den Niederhaltern für die äußeren Längsstege zusätzlich Niederhalter für ein oder mehrere dieser inneren Langsstege vorgesehen. Diese werden dabei vorzugsweise senkrecht unter der Matrixführungswalze auf der Etikettenmaterialbahn installiert.In the event that the matrix grid belt has inner longitudinal webs, additional hold-downs are preferably provided for the one or more of these inner longitudinal webs in addition to the hold-down devices for the outer longitudinal webs. These are preferably installed vertically under the matrix guide roller on the label material web.
Besonders vorteilhaft ist es, wenn der senkrechte Abstand zwischen der Matrixführungswalze und der Bahnlaufebene des weitergeführten Etikettenmaterials einen Wert einnimmt, der 1/10 - 5/10 der Bahnbreite des Etikettenmaterials entspricht. Bevorzugt sind hierbei Werte von 2/10 - 4/10 der Bahnbreite, und ein Bereich von 2,5/10 - 3,5/10 ist besonders günstig.It is particularly advantageous if the vertical distance between the matrix guide roller and the web running plane of the continued label material assumes a value, which corresponds to 1/10 - 5/10 of the web width of the label material. Values of 2/10 - 4/10 of the web width are preferred, and a range of 2.5 / 10 - 3.5 / 10 is particularly favorable.
Weiterhin ist die Matrixführungswalze vorzugsweise mit einer besonders glatten Oberfläche, z.B. durch Politur oder Beschichtung, mit Kugelkäfigen oder Linearlager ausgestattet, sodaß die freie Beweglichkeit der äußeren Längsstege des Matrixgitterbandes gewährleistet wird. Als besonders günstig haben sich hierbei Linearlager erwiesen.Furthermore, the matrix guide roller is preferably with a particularly smooth surface, e.g. by polishing or coating, equipped with ball cages or linear bearings, so that the free movement of the outer longitudinal webs of the matrix grid belt is guaranteed. Linear bearings have proven to be particularly favorable.
Eine weitere bevorzugte Ausführungsform des Verfahrens sieht vor, daß das Matrixgitterband bei seiner Führung über die Matrixführungswalze um einen Winkel beta = 5-120° aus der ursprünglichen Matrixebene abgelenkt wird.Another preferred embodiment of the method provides that the matrix grid belt is deflected from the original matrix plane by an angle beta = 5-120 ° when it is guided over the matrix guide roller.
Der obige Winkel beta wird günstigenfalls auf einen Wert von 10-90° eingestellt, wobei ein Wert von 30-70° insbe¬ sondere bevorzugt ist.The above angle beta is advantageously set to a value of 10-90 °, a value of 30-70 ° being particularly preferred.
Die Ablenkung um den Winkel beta erfolgt bevorzugt durch das Zusammenspiel der Matrixführungswalze und einer Umlenkwalze, die zur Einstellung des Winkels beta ent¬ sprechend zueinander positioniert werden.The deflection by the angle beta is preferably effected by the interaction of the matrix guide roller and a deflection roller, which are positioned accordingly to one another to set the angle beta.
Das Matrixgitterband wird schließlich vorzugsweise mit einer Zugspannung von 1-2 N/mm über die Niederhalter, die Matrixführungswalze und die Umlenkwalze geführt.Finally, the matrix grid belt is preferably guided with a tension of 1-2 N / mm over the hold-down device, the matrix guide roller and the deflection roller.
Die für die Durchführung des obigen Verfahrens geeignete Vorrichtung umfaßt Abrollmittel für das Etikettenmaterial, ggf. Druckmaschinen, weiterhin Stanz- und Schneidwerk¬ zeuge, ggf. Perforierungsmittel, Anlagen zur Führung des abgerollten Etikettenmaterials und des abgezogenen Matrixgitterbandes des Obermaterials und ist gekennzeich¬ net durch je einen Niederhalter für die äußeren Längsstege des Matrixgitterbandes und eine Matrixführungswalze für diese Längsstege.The device suitable for carrying out the above method comprises unrolling means for the label material, possibly printing machines, further punching and cutting tools, possibly perforating means, systems for guiding the unrolled label material and the removed one Matrix grid belt of the upper material and is marked by a hold-down device for the outer longitudinal webs of the matrix grid belt and a matrix guide roller for these longitudinal webs.
In einer bevorzugten Ausführungsform ist die Matrix¬ führungswalze mit einem Linearlager ausgestattet.In a preferred embodiment, the matrix guide roller is equipped with a linear bearing.
Bei einer weiteren Ausgestaltung der obigen Vorrichtung sind Niederhalter für ein oder mehrere, innere Längsstege des Matrixgitterbandes vorgesehen.In a further embodiment of the above device, hold-down devices are provided for one or more inner longitudinal webs of the matrix grid belt.

Bei der Herstellung des Etikettenbogens wird das Etiket¬ tenmaterial über je einen Niederhalter (1) für die äußeren Längsstege geführt, wobei das Matrixgitterband aus dem Obermaterial in einem Winkel alpha mittels der Matrix¬ führungswalze (2) abgehoben wird. An der Matrixführungs¬ walze (2) angebrachte Linearlager (3) ermöglichen hierbei, daß die über die Matrixführungswalze (2) geleiteten, äußeren Langsstege des Matrixgitterbandes in Richtung der Querstege des Gitters beweglich sind. Für den Fall, daß das Matrixgitterband innere Längsstege aufweist, sind senkrecht unter der Matrixführungswalze (2) für ein oder mehrere dieser Stege Niederhalter (4) vorgesehen. Die Matrixführungswalze (2) und die Bahnlaufebene (6) des weitergeführten Etikettenmaterials weisen weiterhin einen senkrechten Abstand b zueinander auf. Die Matrix wird schließlich über eine Umlenkwalze (5) um einen Winkel beta von der ursprünglichen Matrixebene abgelenkt.During the production of the label sheet, the label material is guided over a hold-down device (1) for each of the outer longitudinal webs, the matrix grid tape being lifted from the upper material at an angle alpha by means of the matrix guide roller (2). Linear bearings (3) attached to the matrix guide roller (2) make it possible for the outer longitudinal webs of the matrix grid belt guided over the matrix guide roller (2) to be movable in the direction of the cross webs of the grid. In the event that the matrix grid belt has inner longitudinal webs, hold-down devices (4) are provided vertically below the matrix guide roller (2) for one or more of these webs. The The matrix guide roller (2) and the web running plane (6) of the continued label material also have a vertical distance b from one another. The matrix is finally deflected from the original matrix plane by an angle beta via a deflection roller (5).
Durch das beanspruchte Verfahren ist es möglich, eine übermäßige Dehnung der Querstege und eine Kerbwirkung in den Knotenpunkten von Längsstegen und Querstegen zu verhindern bzw. gering zu halten, sodaß kein Bruch des Matrixmaterials quer zur Bahnlaufrichtung auftritt. Der Abzug der Querstege erfolgt gleichzeitig von beiden Längsseiten des Etikettenmaterials fortschreitend von außen nach innen, und der Winkel zwischen weitergeführter Etikettenmaterialbahn und abgehobenem Matrixquersteg liegt über den gesamten Abzugsbereich so, daß sich eine geringe Trennkraft einstellt. Mit dem beanspruchten Verfahren ist es möglich, Produktionsgeschwindigkeiten (Bahnlaufge¬ schwindigkeiten) von > 100 m/min, insbesondere bis zu 200 m/min, einzustellen.The claimed method makes it possible to prevent or keep excessive stretching of the crossbars and a notch effect in the nodes of the longitudinal webs and crossbars, so that there is no breakage of the matrix material transverse to the web running direction. The crossbars are simultaneously withdrawn from both longitudinal sides of the label material progressively from the outside inwards, and the angle between the continued label material web and the raised matrix crosspiece lies over the entire withdrawal area so that a low separation force is obtained. With the claimed method it is possible to set production speeds (web running speeds) of> 100 m / min, in particular up to 200 m / min.

The separation force between the silicon paper (carrier material) and the paper (upper material) is 0.10 ± 0.03 N / 25 mm (Finat test method FTM3) processed in a label printing machine to flat label sheets, so that the carrier material of the label sheet assumes the format A4.
Hierbei wird zunächst das Etikettenmaterial so passergenau durch eine rotative Stanze geführt, daß das Obermaterial im Format 296,0 x 209,0 mm herausgestanzt wird. Weiterhin erfolgt die Stanzung so, daß der Abstand zwischen zwei aufeinander folgenden Obermaterialformaten 1,0 mm beträgt.Here, the label material is first passed through a rotary punch so that the upper material is punched out in the format 296.0 x 209.0 mm. The punching is also carried out in such a way that the distance between two successive upper material formats is 1.0 mm.
Die um die herausgestanzten Formate hierumliegende Obermaterialmatrix wird über je einen Niederhalter (1) für die äußeren Längsstege, eine Matrixführungswalze (2) mit Linearlager (3) und eine Umlenkwalze (5) mit Winkeln alpha = 30° und beta = 60° und bei einem Abstand b = 60 mm, sowie mit einer Bahnlaufgeschwindigkeit von 150 m/min abgezogen.The outer material matrix around the punched-out formats is held down by a hold-down device (1) for the outer longitudinal webs, a matrix guide roller (2) with linear bearing (3) and a deflection roller (5) with angles alpha = 30 ° and beta = 60 ° and at one Distance b = 60 mm, and deducted at a web running speed of 150 m / min.
Anschließend wird die weitergeführte Etikettenmaterialbahn mit in Bahnlaufrichtung rotierenden Schneidmessern links und rechts so beschnitten, daß sie eine Breite von 210,0 mm aufweist, und die linke und die rechte Träger¬ materialkante je 0,5 mm über die Obermaterialkante hinaus- stehen.Subsequently, the continued web of label material is trimmed on the left and right with cutting knives rotating in the direction of web travel so that it has a width of 210.0 mm, and the left and right edge of the substrate material each protrude 0.5 mm beyond the upper material edge.
Die seitlich beschnittene Endlosbahn wird durch einen rotativen Querschneider so passergenau geführt, daß die freiliegende Trägermaterialzone in der Mitte zwischen zwei Obermaterialformaten quer zur Bahnlaufrichtung durch¬ trennt wird.The laterally trimmed continuous web is guided so precisely by a rotary cross cutter that the exposed carrier material zone is cut in the middle between two upper material formats transversely to the web running direction.
Die resultierenden Etikettenbogen werden in einen Senk¬ stapel geführt und übereinander gestapelt. Derart hergestellte Etikettenbogen lassen unter dem Mikroskop bei 420-facher Vergrößerung keine Haftkleb- stoffpartikel an den äußeren Trägermaterialschnittkanten erkennen. Auch nach einem Durchlauf von 10000 solcher Etikettenbogen durch einen Laserdrucker sind unter dem Mikroskop bei 420-facher Vergrößerung keine Haftklebstoff¬ partikel auf den Transportwalzen und auf der Halbleiter- trommel beobachtbar.The resulting label sheets are fed into a sink stack and stacked one above the other. Label sheets produced in this way show no pressure-sensitive adhesive particles on the outer edges of the carrier material under the microscope at a magnification of 420 times. Even after 10000 such label sheets have been passed through a laser printer, no pressure-sensitive adhesive particles are observable on the transport rollers and on the semiconductor drum under the microscope at a magnification of 420 times.

Weiter¬ hin ist der Abstand zwischen zwei in Bahnlaufrichtung aufeinander folgenden Formaten auf 1,0 mm festgelegt.A 428 mm wide roll of label material of the type mentioned in Example 1 is punched out by rotation, so that two adjacent outer material formats each with 296.0 x 209.0 mm are punched out. The distance between the adjacent formats is 2.0 mm. Furthermore, the distance between two successive formats in the web running direction is fixed at 1.0 mm.
Anschließend wird die Obermaterialmatrix über je einen Niederhalter (1) für die äußeren Längsstege, eine Matrix¬ führungswalze (2) mit Linearlager (3) für die äußeren Längsstege, einen Niederhalter (4) für den inneren Längs¬ steg, der senkrecht unter der Matrixführungswalze (2) positioniert ist, und eine Umlenkwalze (5) abgezogen. Die Winkeleinstellung und die Bahnlaufgeschwindigkeit erfolgt gemäß Beispiel 1, der Abstand b beträgt 110 mm.Then the upper material matrix is held down by a hold-down device (1) for the outer longitudinal webs, a matrix guide roller (2) with a linear bearing (3) for the outer longitudinal webs, and a hold-down device (4) for the inner longitudinal web, which is perpendicular to the matrix guide roller (2) is positioned, and a deflecting roller (5) is pulled off. The angle setting and the web running speed are carried out according to Example 1, the distance b is 110 mm.
Die Etikettenmaterialbahn wird schließlich mit in Bahn¬ laufrichtung rotierenden Schneidmessern links, mittig und rechts und danach mit einem rotativen Querschneider in der Mitte zwischen zwei aufeinander folgenden Obermaterial¬ formaten quer zur Bahnlaufrichtung so geschnitten, daß jeweils nebeneinander zwei Etikettenbogen des Formats 297,0 x 210,0 mm entstehen, wobei die linke und die rechte Trägermaterialkante je 1,0 mm, und die obere und die untere Trägermaterialkante je 0,5 mm über die Ober¬ materialkante hinausstehen.The label material web is finally cut with cutting knives rotating in the web running direction left, center and right and then with a rotary cross cutter in the middle between two successive upper material formats transversely to the web running direction in such a way that two label sheets of the format 297.0 x 210 , 0 mm arise, the left and the right Base material edge each 1.0 mm, and the upper and lower edge of the base material each protrude 0.5 mm above the upper material edge.
Die mikroskopische Untersuchung gemäß Beispiel 1 läßt keine Haf tklebstof fpartikel an den Trägermaterialschnitt¬ kanten und auf den Transportwalzen bzw. der Halbleiter¬ trommel erkennen. The microscopic examination according to Example 1 shows no adhesive particles on the edges of the carrier material and on the transport rollers or the semiconductor drum.
